I recently had a DMCA takedown request on YouTube, It was for a <1 minute video clip of a free show from Morris Day and the Time at the MN state fair I took with my phone. To be allowed to view YouTube videos I had to go through a copyright boot camp and learn what is copyrighted work (Hint: everything you can see, hear, or touch).

Giant pain in the ass and just makes me wonder why anyone would post anything to YouTube now that you can be shut down because someone didn't like your video and issues a DMCA takedown request.
